Definitions

  • This invention relates to a method of manufacturing a fabric for the inked ribbon used in the printers such as impact type serial dot and line printers.
  • the inked ribbon used in the impact type printers the conventional spool type is decreasing, and the cassette type having the inked ribbon in the form of a long tape folded and housed in a cassette has become the main.
  • the inked ribbon of the cassette type had a shortcoming to produce print spots, or hot spots as generally called, at the folded parts of the ribbon.
  • a cloth composed of warps having a twist of 100 T/m or more and wefts of a twist of 0 to 300 T/m has been used. That is, to reduce the processing cost, the so-called non-twisting is being realized with the twisting process omitted for the wefts and the original twist of 30 T/m or less of the material yarn utilized for weaving. But, here, if such non-twisting is applied to the warps, the hot spots are generally produced, and so the inked ribbon is applicable only to limited uses such as spool type having hot spots scarcely produced.
  • Patent Publication No. SHO 61-24487 it is described to disturb the fiber orientation of the cloth for inked ribbon with a high pressure water stream in order to dissolve the reel marks and improve the absorption of ink, but nothing is described of the method of dissolving the hot spots with the twist of the warp reduced.
  • the fabric for inked ribbon of the present invention has the following composition.
  • the fabric for inked ribbon according to the present invention is composed of a cloth having multifilaments of a twist of 30 T/m or less used for the warp, and it is characterized in that the fiber orientation in said multifilament is disturbed through high pressure liquid treatment.
  • the method of manufacturing the fabric for inked ribbon according to the present invention is characterized by treating a cloth composed of warps of multifilaments of a twist of 30 T/m or less with a flow of high pressure liquid.
  • FIG. 1 shows the standard for evaluation of hot spots. That is the conditions of hot spots of various ranks of ribbons in solid printing.
  • a fabric for inked ribbon scarcely producing hot spots by treating a cloth composed of multifilaments of a low twist of warps with a high pressure liquid.
  • the fabric for inked ribbon of the present invention has the orientation of fibers in the filaments disturbed by the high pressure liquid treatment and thus has the voids in the fabric increased, and so it is distinguished in absorption of ink.
  • the effect of improving the hot spots is readily obtainable, and the ink absorption is increased.
  • the fabric shrinks more or less, and here by taking such shrinkage into account and weaving to a rather low fiber density, it is possible to provide a product of a desired fiber density and thickness.
  • the material for the multifilament under the present invention there may be listed the polyamide fiber, polyester fiber, polyacryl fiber and polyvinyl fiber. But, form the durability of the fabric, the polyamide fiber and polyester fiber are preferable, and nylon 66 and nylon 6 are particularly preferable.
  • the fabric constituting the inked ribbon is composed of a cloth having the foregoing fiber used for the warp as well as weft.
  • the total denier of these yarns is preferably 20 to 100D or, more preferably, 40 to 70D, and the single yarn denier of the fiber constituting the yarn is preferably 1 d to 3d.
  • the textile density of the fabric is preferably 150 to 20 yarns/in. for the warp and 100 to 140 yarns/in. for the weft but is not limited thereto.
  • plain weave For the texture of the fabric, plain weave, derivative plain weave, twill and saten are preferably used but are not limited thereto.
  • the inventors examined the contribution of the warp and found that the warp would contribute to increasing the ink absorption but not so much as the weft for improvement of the hot spots.
  • the high pressure liquid treatment under the present invention refers to a method of spouting a liquid through a small hole under a high pressure to have it hit the fabric.
  • the liquid may contain an additive such as solid particles, an organic solvent or a surface active agent.
  • the diameter of the nozzle spouting water is preferably 0.1 to 0.4 mm or, more preferably, 0.2 to 0.35 mm.
  • the fabric treatment speed is preferably 5 to 100 m/min or, more preferably, 20 to 80 m/min.
  • the high pressure liquid treatment may be made in any of the scouring, drying and heat setting processes of the fabric but is efficiently made after scouring.
  • the fabric thus obtained has hot spots scarcely produced, equally to, or much more than, the conventional fabric composed of yarns of a twist of about 100 to 300 T/m through additional twisting and is thus distinguished as a fabric for inked ribbon.
  • An inked ribbon (10 m long) prepared as above is set in a cassette for 9-pin dot printer (product of Tokyo Denki, model M-1550), and the cassette is set on the printer for solid printing, and any hot spots are observed with naked eye.
  • the standard of evaluation is shown in FIG. 1, viz.
  • the fabric to be tested is melt cut into a size of 10 cm ⁇ 10 cm to form a test specimen, then its weight (A) is measured.
  • the test specimen is soaked in an oil ink, and defoaming by vacuuming, the ink is well permeated into the test specimen.
  • the test specimen is held between filter papers to remove excessive ink through a mangle. Then, changing the filter papers, the test specimen is allowed to pass through the mangle twice to completely remove the excessive ink, and the weight (B) of the ink containing ribbon is measured.
  • the ink absorption is calculated by the formula
  • Two kinds of yarns were prepared: a 40 denier/34 filament yarn of an original twist of 13 T/m, ahd a yarn having an additional twist of 273 T/m made to the first yarn to a total twist of 283 T/m together with the original twist of 13 T/m.
  • plain fabrics were woven in a water jet room, and they were scoured and dried according to the conventional method. Thereafter, Examples 1 through 5 had the high pressure water jet treatments shown in Table 1 rendered and, after drying, finish setting made. References 1 and 2 were directly subjected to finish setting without high pressure water flow treatment.
  • Example 5 had the hot spot greatly improved and were good in ink absorption, provided Example 5 had the texture slightly deviated, as compared with the others, probably on account of the higher water pressure.
  • Reference 1 is of the same fabric design to the inked ribbons generally used for the 9-pin dot printer, but the hot spot is of ⁇ level.
  • Reference 2 is worse than Reference 1 in the level of hot spot.
  • Examples 6 through 10 had the high pressure water jet treatments shown in Table 2 and, after drying, finish setting given respectively.
  • References 3 and 4 were directly subjected to finish setting without high pressure water jet treatment.
  • Reference 3 is of the same fabric design to the inked ribbons generally used for the 24-pin dot printer, but the hot spot is of X level.
  • Reference 4 is a fabric for inked ribbon comprising warps of multifilament yarns of a twist of 30 T/m or less and has no high pressure water jet treatment rendered. It will be seen that the level of the hot spot is worse than that of Reference 3.
  • the inked ribbon comprised of the fabric of the present invention is very suitable and advantageous for the printers using the cassette type ribbon which is the main of the form of the inked ribbon in recent years. It scarcely produces hot spots and is distinguished in ink absorption. Furthermore, it uses the warp of a very low twist of 30 T/m or less and is thus economically produced.
